The rookie ladder sees a shakeup out of the All-Star break, and there is a new entrant to the list who shoots all the way up inside the top three slots.

Kyrie Irving, Ricky Rubio and Isaiah Thomas are all incredibly exciting rookie point guards in a league that is filled with a plethora of young talent at the position.

There are also some very promising big men who should all be playing larger roles for their respective teams in the second half of the season, and it will be interesting to see who emerges from the field with an increased opportunity.

It's about time this kid got national attention.

The No. 60 overall pick of the 2011 draft has been a spark since being inserted into Sacramento's starting lineup, and he's having more success in that role than almost anyone thought he possibly could.

Averaging 19.2 points, 3.8 rebounds and 6.8 assists on 50.8 percent shooting in five games as a starter, it shouldn't come as a surprise that the Kings have looked like a different team since Thomas was handed a more substantial role.

He spaces the floor incredibly well and has impressive court vision, and this is a player who is very capable of holding value despite being undersized.
